Abstract
Alnus nitida (Spach) Endl. belong to the family Betulaceae. It is distributed in the western Himalayas and the Hindu Kush regions of the Sino-Japanese belt of northern Pakistan. This study was designed to investigate the morpho-anatomical variation in different populations of Alnus nitida (Himalayan Alder). Preliminary, a variation was observed in the size of both male and female catkins. Similar variations were observed in pollen morphology in different populations of the species. The micronutrients in soil and environmental conditions are the main drivers of these variations. These palynological, anatomical, soil characteristics and environmental conditions were analyzed through multivariate statistical software i.e., PCORD and CANOCO. It was observed an efficient accumulator of all heavy metals as revealed by the values (>1) of Biological Accumulation Coefficient (BAC) in shoots, BCF in roots and the Translocation Factor (TF). Detailed morpho-anatomical and palynological variations in Alnus nitida were enlisted. The palynological and anatomical variations were not enough to define the taxonomic status of different populations. However, further molecular studies will be essential to clear the genetic diversity in these populations
